Feed Handlers

Feed Handlers are publishers that manage data that arrives directly from an exchange, like the NYSE, or a consolidated service provider like Reuters, and then send the data (using the Publisher API) over the network to one or more subscribers.

RAP includes a Demo Feed Handler. Demo Feed Handler is a Sybase feed handler that reads comma-delimited market data from a demo file (STOCK_QUOTE.csv). This component is intended to help developers become familiar with the Publisher API and demonstrate network message flow.

• Publisher API
  RAP includes a Publisher API library which is used by feed handlers to format incoming market data and send the data to subscribers using UDP multicasting.
• FAST Feed Handler
  The FAST Feed Handler connects directly to a market data feeds, receives FAST-encoded messages, decodes the data, and makes the decoded data available to the message handler plug-in.
• Demo Feed Handler
  The Demo Feed Handler is included to demonstrate network message flow and familiarize developers with the Publisher API.
